## Statement

In the registered same-block (1,3) Peirce carrier, the cubic invariant extracts the middle vacuum weight λ2 = 1.

## Caution

The unit carrier eigenvalue does not identify the physical Higgs, the renormalized coupling or the Planck scale.

## Primary source

Appendix A, §A.6, W01: internal carrier result, PDF p.145: "the cubic invariant, evaluated on the carrier field ΦH in the (1, 3) Peirce block, extracts the middle vacuum weight λ2 = 1."
